PNEUMATIC INFORMATION
AIR SUPPLY INSTALLATION
If compressor has a good dryer unit, use black pickled pipe. When a dryer unit is not installed,
use galvanized or copper pipe. To perform reliably, a pneumatic tool requires a continuous
source of clean, water-free air at adequate pressure.
Never operate this tool using a bottled air or gas source.
Bottled air/gas sources do not provide consistent operating pressure
A filter-regulator-lubricator
(FRL) unit must be installed as
close to the air tool as
possible, preferably within 10
feet. It should be placed in a
convenient location where it
can easily be drained,
adjusted, and filled with oil.
The air hose must have at least
a 3/8" I.D. A quick disconnect
socket fitting is installed on
the stress spring end of the
hose for convenient hookup to
the air tool.

Filter and lubricator bowls are made of polycarbonate material. Do not install where bowls may
be exposed to materials incompatible with polycarbonate. Certain oils, solvents, and chemicals
or their fumes can weaken these bowls and possibly cause them to burst. Clean only with warm
water. A cut-off valve placed ahead of the filter will be useful when cleaning the filter or
replenishing the lubricator.

PNEUMATIC INFORMATION, Continued
MOISTURE
Moisture is always present in air lines due to condensation within the lines as the air cools.
Steps must be taken to remove this moisture and to keep it from the air tool. This is because
water tends to wash away lubricants and cause corrosion, sticking and failure of internal parts.
The main line should be pitched so the far end terminates in a water leg. Branch lines are taken
from the top of the main, never off the bottom. Every branch should have a water leg at its
lowest point, with a drain cock which is drained daily.
If these precautions are taken and water is still present, an after cooler and a moisture separator
are required between the compressor and the air receiver tank. A large air line separator can be
installed in the air tool line, but precautions must be taken to insure that it will be drained daily,
before the air tool is operated.
Water in air lines is a constant threat to the proper operation of air tools. Even near freezing
operating conditions, a good refrigerant type dryer is essential. A good dryer will remove 95%
or more of water right at the compressor. The remaining moisture is removed at the water leg in
the piping system or in the filter.
NOTE: Additional information is available in the Signode publication, "Air Supply Manual" (Part
No. 186038). If you have any questions, contact your local Signode Representative.
LUBRICATION
The air tool must be properly lubricated. This is achieved by keeping the air line lubricator filled
with oil and correctly adjusted. Without proper lubrication, the tool will become sticky and will
be difficult to release from the strap.
Install the lubricator as close to the air tool as possible. The arrow on the lubricator's top
surface must point in the direction of air flow.
For proper operation, oil must drop through the lubricator sight glass at a rate of 4 to 10 drops
per minute. This rate is checked while the air tool is running free. Only 20% of this oil is actually
delivered to the tool. The remaining oil drops back into the oil reservoir. The unit is factory set
and should require no adjustment. If an adjustment is required, the adjusting screw on top of
the lubricator may be turned as marked to reduce or increase the flow of oil.
The correct grade of oil must be used in the lubricator; too heavy an oil will not provide sufficient
lubrication and will cause sticking and sluggish operation of the air tool.
Recommended oils are any good grade of rust and oxidation inhibiting oil with a viscosity of 80-
120 S.U.S. at 100 degrees Fahrenheit. (0.15 to 0.25 cm2/sec. at 38 degrees Celsius), such as:
Non Fluid Oil Co., grade #LS-1236
Signode oil - Part No. 008556
If necessary, use SAE #5 or SAE #10 non-detergent, cut 1 to 1 with kerosene.
77
NOTE: Some oils contain anti-wear additives which may disable the tool. Be certain to use
recommended oil.
Several drops of lubricator oil added to the inlet of the air line each day will help insure good
operation. A noticeable reduction of performance can usually be corrected by squirting a few
drops of oil into the air line.
COLD WEATHER OPERATION
If a tool does not operate satisfactorily in freezing temperatures, certain steps can correct the
problem. The following steps can be taken to improve cold weather operation of the tool:
a. An air line dryer adjacent to the compressor.
b. Use lubricant recommended by Signode. Signode has tested the use of anti-freezes, none
work well in air tools; the tool will gum up when anti-freezes are introduced and will not
function properly. The best lubricant for freezing weather is the 1 to 1 oil and kerosene
combination.
c. If possible, run the air supply line to a indoor located Filter-Regulator-Lubricator or relocate
the F-L-R to a warmer operating area.

Strap breakage hazard. Strap can break during tensioning if inlet air
pressure to the tool exceeds 90 psig. Strap breakage can result in
severe personal injury. Maximum operating pressure is 90 psig.
TOOL INSTALLATION
To operate effectively, your tool must be installed properly. This installation includes proper
suspension of the tool over the package to be strapped, correct placement of a strapping
dispenser to provide a continuous easy supply of strap for the application, and a satisfactory air
supply with air line pressures being maintained within the specified range.

TOOL OPERATION
Wear safety glasses which conform to
ANSI standard Z87.1 or EN 166. Stand to
one side of the strap while tensioning.
Make sure all bystanders are clear before
proceeding.
1. Raise the gripper wheel by pressing
down on the pawl handle. Insert the
bottom strap and release the pawl
handle. Allow one foot of strap to extend
beyond the front of the tool.
2. Thread seals properly on to upper strap.
3. Thread strap in to the windlass and
under the strap pin. Strap should extend
4" - 8" beyond the windlass.
NOTE: Make sure straps are fully seated
against the base.
4. Pull out slack, turn valve clockwise to
rotate windlass about 1/2 turn to secure
strap in the windlass.
5. Thread seals properly on to bottom
strap.
99
6. While standing to one side of the strap
line, rotate the valve collar clockwise to
tension strap allowing motor to stall out
at desired tension.
If for some reason the gripper will not
energize, do not try to energize using the
pawl handle, as this will result in
disengagement of the ratchet wheel.
Apply light machine oil to the pivot pin
(5), until the lever moves freely.
7. At the end of the tensioning cycle, use
sealing tool to notch or crimp seals.
8. After sealing the strap, rotate the valve
collar counterclockwise to unwind the
windlass. Note tab end of strap in
windlass. When this becomes loose, the
tool will be easily removed. The valve
collar is spring loaded to the reverse
direction so that when released, the
valve will return to neutral.
Lift the pawl handle thereby disengaging
the ratchet wheel. Then press down on
the pawl handle and rotate the tool off
the strap in a counterclockwise
direction.
